This is possible; however it is worth noting that installation costs may be quite high thus the overall cost is likely to increase. Where possible it is more cost effective to install a single powerPerfector unit at the main incomer, as this allows savings to be aggregated across all the equipment on the site, and the powerPerfector is also able to improve the efficiency of the supply transformer by protecting it from site-generated harmonics. This extra efficiency gain will result in additional savings for clients who are metered on the HV (high voltage) side of their transformer.
